GTI 337/20th Anniversary :: Getting Two Codes - Engine Temperature Too Low - Turbo Boost Pressure Too High?
Engine temperature too low. Turbo boost pressure too high. The car has the APR 93 octane program, carbonio intake, and silicone TIP.
What could be causing these codes? The car gets up to temp (190) real quick and stays there, and I don't feel a fluctuation of boost.
Golf VI R :: No Turbo Boost - Weird Sound When Hit The Gas
I have a 2012 R with 85,000 miles, APR chip running 93 octane with a HPFP and VWR cold air intake. I was driving my car today (slow driving on highest) and all of a sudden I felt no turbo boost, and heard a weird sound whenever I hit the gas. Car moved but would not get above 3500 rpms and couldn't really get past 60 mph. Again, absolutely no boost (I have a boost gauge as well to verify).
About to drop off the car at a shop but had a couple questions:
1. If the turbo is blown, can I still drive the car to the shop (not too far) without damaging the engine itself?
2. if the turbos needs to be replaced, what are my options besides getting the stock turbo replaced, without getting some crazy setup? This is my daily driver and I don't want to spend money beyond what I need to get it fixed, but it there is a stronger more reliable turbo for about the same as a OEM, I would want to consider... Also price for OEM replacement??
3. Without the mechanic looking at it, I'm just assuming it's the turbo but what else could be the issue? All the lines looks intact and intake is fitted correctly. I did have issues with my cam follower getting damaged at 45,000 miles (there was a hole in it) and I have been replacing it every 20,000 miles since. Didn't have any issues for 40,000 additional miles, but could damage to that cause turbo failure?
Golf/GTI VI :: Boost Leak Between Exhaust Manifold And Turbo
I have a leak between the turbo and the exhaust manifold. The golden clamp (c-clamp? v-clamp?) broke, and now there is a gap between the two. The dealership doesnt cover it under powertrain warranty (my car has passed regular warranty) but worst of all they do not sell the clamp on its own.
I posted a link to a picture below, it isn't my turbo.

Golf IV / Jetta IV :: Turbo Flutter Over 20 Pounds Of Boost
I have an 03 GTI 1.8t with the stock K03s turbo and i used to boost to 25 pounds. Had to put a new motor in and now i when i boost above 20 pounds i get turbo flutter and loose boost. I can boost anywhere up to 20 pounds and the turbo doesn't flutter at all.
I had a spring on my waste gate which i have taken off and it changed nothing. I tried a different diverter valve and it didn't change anything. I unplugged the MAF to see if the N75 or the there was a boost leak and extra air wasn't being monitored but still changed nothing. It has nothing to do with my RPM range just when i boost over 20 pounds. I am planning on doing a leak down test to make sure there isnt a boost leak....
Golf/GTI VI :: Blown Turbo / Slight Boost Leak
Recenly, i feel like i haven't been hitting boost, so i went to get an oil change last week. I did the oil change, and everything seemed ok, I thought it might have been a slight boost leak. This morning i check my drive way to see a little oil on it. So i check the dip stick and the oil level is already at a minimum. Do you think i have a blown turbo due to the oil drop and lack of boost. It hasn't been a 100 mi since the oil change either.

2012 TDI ... OK so out of nowhere, my car is making loud turbo whoosh noise, while I love the way it sounds, it's not normal or intentional, so I don't like it lol. I have an AWE intake, and a gutted turbo resonance damper. Is been fine and same sound ever since those mods but now out of nowhere it is really loud with the whooshing of the turbo.
Small video of it... [URL] ....
Pictures of turbo area .....
Anything look wrong? I circled that one area but wouldn't know if that's normal or not....
Golf IV / Jetta IV :: New Turbo Installed / Wastegate Opens Early Without Building Much Boost
I recently installed a k04 turbo, when I try and accelerate hard my wastegate just seems to open up very quickly without building much boost. I don't have a boost gauge or anything like that installed. Do I start by adjusting the wastegate actuator, or install MBC. Pretty new to this still.

2003 jetta gls 1.8t 5spd - gts stage 1 tune(gonzo stage 2)
tt 2-1/2" downpipe with high flow cat
turbo smart splitter valve(set to divert only)
turbo inlet pipe
homemade intake with k&n filter
stock n75 valve (f)
So in first through 3rd gear my car gets 20psi of boost then at 3,500 ish rpm smoothly starts to lower down to 15psi. but in forth and 5th gear the boost drops faster, enough so the diverter valve actually opens. then the boost will bounce up and down, around 15psi. the car still accelerates but with obvious power loss.
Is my diverter valve not "firm" enough? it is adjustable, so I've tightened it as much as it can. it doesn't seem to change anything. it came with spring spacers to make it tighter, but I haven't tried that yet.
Is it something with the tune? not enough fuel, need bigger injectors? The problem is only at about 100mph, so its not a big deal. I would like to get it straightened out if possible.
Ford 6.0L Power Stroke Diesel :: 2003 - Turbo Whistling Very Loud At Idle / High RPMs?
So I just purchased my first diesel a couple weeks ago (2003 f250 Lariat). I love it! However, I'm having concerns about my turbo whistle on it. At idle and while in higher RPMs is sounds ridiculously loud (even at 0 PSI in the boost). I've been doing my research on it and I know the 03's have the loudest sounding turbos because they have less vanes than the later models. I know without a video it's going to be hard to diagnose, but I am wondering if a loose boot would cause a turbo whining sound through the exhaust? I have yet to hear ANY other diesel in person that has a turbo whine as loud as mine.
View 14 RepliesGolf VI R :: Strange High Pitched Whine And No Boost
I recently noticed that my Golf R was making a strange high pitched whine and it seemed like there was no boost. I took my car to the dealer, and it turns out that part of the CAI broke off (a mounting component) and made its way into the turbo, effectively destroying it.
My dealer was initially intending to cover the turbo under warranty (prior to investigation), but now that it is clear that a failure in the CAI caused the issue, they cannot (obviously) cover it under VW warranty. Unitronic CAI failure led to turbo failure.
The serviced manager did some research prior to getting back with me, and was somewhat puzzled since the Unitronic CAI displayed on their website looked slightly different from mine in that the component that failed was not there. The service manager called Unitronic and learned that the failed component was a known issue (it had apparently failed before), and thus they modified the design - hence the picture of the revised version did not match the older version that was installed on my Golf R. The Unitronic rep offered to replace the CAI - but did not mention anything about the failed turbo (when he spoke to the service manager).
I found the following thread which illustrates that this was a known issue: [URL] .... I just wish I had found out about this before it failed.
Golf IV / Jetta IV :: High Pitched Noise While Under Boost
I'm having a strange, very high-pitched, noise that seems to be coming from my turbo or (possibly) somewhere else in the engine bay. It sounds very screechy, and it may be paranoia, but I believe it also may have a slight metallic sound to it.
It all started yesterday after changing the thermostat housing for the third time in 2 days (autozone sold me a faulty, warped, housing that leaked after install). During this repair the engine never overheated (it did however leak fluid and go a little low) and the main point for replacement was a stuck thermostat. After finally getting it fixed I took it for a test drive and noticed the horrid noise after hitting a good amount of boost (no gauge installed). The noise occurs when boosting and doesn't happen when spooling in the 3k-4k range. I had no hint of the noise before this.
There doesn't seem to be any drop in performance and it still pulls hard. Hoping this to be a loose exhaust connection or boost leak. May be spooling sound escaping.
Mods:
- short ram air intake with an aem filter
- 3" turbo-back exhausted
- revo chipped
- 4 bar fpr
Golf IV / Jetta IV :: 1.8t - Bogged Down And Misfiring When Go Into High Boost
I'm having a misfire issue on my 1.8t. When I go into high boost I'm getting bogged down and misfiring.
I plugged in my obd2 adapter and it gave me a misfire on cylinder 3. I since cleared the code to try and see if it was a coil pack by switching it to another cylinder, but now the cel won't come back on although the problem persists.
I have recently changed the plugs and the car was fine. I then added a fuel injector treatment and the misfire started shortly afterwards. (coincidence perhaps). It's frustrating as I can't rule out coil packs as my cel won't come back on and my code reader is not displaying any faults.
I did previously have a cel with something about fuel trim bank 3? I am also sure I have a boost leak as the car whistles pretty loud under boost.
Also worth mentioning I have a bit of white smoke sometimes but I'm not using oil or coolant and they are not mixing either. I'm at the end of my tether with this car and just want to try get it back to normal.
Golf VI R :: High Pitch Screech In Boost And While Letting Off Gas
The symptoms are as follows.
-No change in performance, functionality, or spooling.
-Loud intermittent screeching noise when building boost above 3500 RPM
-Can only describe the sound as air escaping from a tiny hole, VERY similar to warn brakes, that kind of screech. The intermittent part I would describe as if you were tapping your brakes (and they were screeching) rapidly, so on off on off very quickly.
-Also happens when I let my foot off the gas (Also above 3500 RPM)
-Car has CTS Turbo Intake, 42DD Downpipe, and APR stage 2 software.
Golf VI R :: Squeal Under High Boost / Sounds Like Air Escaping
I am currently stage 2, drive my car kind of aggressive on a regular basis, and now I hear a squeal under high boost, sounds like air escaping. Boost is not acting any different, I've come to the conclusion that the problem is most likely my revision D DV.
-What does failing REV D sound like???
Golf/GTI VII :: Compression Surge / Turbo Flutter At Low RPM On High Gears
So I'm wondering in a nutshell; in layman's terms... what is compression surge and turbo flutter if you had to summarize it in a few sentences. I was told that its worse with a tune, but even our stock cars have it? I'm not very tech savvy so on the articles I found and read it's said to be bad and basically happening at low RPM on high gears?
View 6 RepliesGolf IV R32 :: Turbo Too Rich At Idle
I've been struggling with this issue for several months now and cant find the issue. My R32 is fully build 6767 turbo and all supporting mods, it has UM 870cc tune and a PRO Maf. Suddenly it started being too rich at idle, wont even start some times and when you press the gas it dies. When MAF is disconnected it will start but when pressing the gas it will die also. Fuel system is a twin 044 Bosch and OEM fuel pump with a FPR. Been trying with different fuel pressure but it doesn't change anything. What could it be the problem?

Golf IV / Jetta IV :: Stalling In High Gears But It First Start Doing This When Hit Boost (3000 RPMs)
I have a golf mk4 1.8T AGU, about one week after i had my k04-023 turbo on and all the Stuff that comes along it started "stall" (don't know if its the right word??) in the High gears, most 5th gear but it first start doing it when i hit boost (3000rpm)
I runs on Stock n75 valve.. I though i could be a boost problem, maybe the Stock system cant handle it? I did install a boost gauge to see if it was the was the problem, and it dont Seem like it. In first it runs from 1.4 bar and drops to 1.2. Same in second and third. But in 4 and 5th it goes to 1.7 bar and drops to 1.4.. I did wonder it maybe the n75 valve cant handle 1.7 bar??
Golf IV / Jetta IV :: 2004 1.8 Turbo Growl At Idle
My wife just got his car and she loves it!. its a 1.8t 5 speed. Runs and drives awesome. She had 2 new beetles before this one with the same motor but they both had 2 1/2 exhaust from the turbo back. The jetta will be done soon but it has this slight growl when its idling sometimes. Doesn't seem like its every time or may be it seems more when its warmed up. We had just changed the timing belt and tensioner and water pump but we did it 2 days after we got it so I am not sure if it did it before or not.
Kinda sounds like a bad needle bearing where when you spin it and can feel little bumps in it...don't know if that makes sense or not. You can kind of feel it when your sitting in it but its hard to say because we just got it. I don't remember the beetles doing it though but may be the exhaust kinda made it less noticeable. It did have a code about exhaust something bank 1?? I am thinking the cat might be bad or the o2 sensors. i have more sensors im gonna try but when i do the exhaust I know the light will be on anyway.
